I wonder if someone actually did some hard testing and theorycrafting regarding frost spec and how good are Orcs with it.
After all, 5% pet damage as well as +SP transferring to the pet is big enough to make a difference.

if all you were going to play was frost then it would probably be the best choice for orc racial but they already hinted at racial changes since a lot of people go horde for the better pve racials. of course they should have said that 6 years ago but hey better late than never... imo they should buff alliance racials instead of nerfing horde

This is something i was very interested in, as the tool tip for TotG suggests Shadow damage only, thus the only Mastery this would scale with is Unholy DK mastery.
I have also wanted to know if the application of TotG can proc an AM

I don't know where you're getting that theory from. The Arcane mastery increases ALL SPELL DAMAGE based on the amount of mana you have unspent. Shadow damage is spell damage. The Frost mastery increases all damage you deal against frozen targets. This doesn't matter against bosses, since the only damaging spell that benefits from Fingers of Frost is Ice Lance, so that and a Brain Freezed Frostfire Bolt are the only spells that benefit from the mastery, but against any trash that you can frost nova and in PvP, Touch of the Grave's damage can be increased by Frostburn. Fire is the only Mage mastery that Touch of the Grave wouldn't scale with.

I have to say, I run as a troll and as frost in pvp it's the best class. Just make a macro for /cast berserk /cast icy vains /use pvp trinket and burn your foes like sticks ( well, except that you use frost xD...but you get the point )
But be warned: if aesthetics are very important to you, DO NOT go for the class with best racials, cause in the end, there isn't much of a gap between classes. As other's said, it's all situational.
